I may be wrong, but I'd guess we won't be seeing Jag or Jazzmaster pickups in the BKP range because there simply wouldn't be sufficient demand to justify the tooling costs (I'm assuming Fender are supplying some of the materials for the Johnny Marr model, rather than BKP making everything from scratch in-house).
As an alternative, you might be able to get your Fender Jag pickups rewound by BKP?
